Parameters:

ratePaymentPeriodPricer - the pricer for RatePaymentPeriod

knownAmountPaymentPeriodPricer - the pricer for KnownAmountSwapPaymentPeriod

Method Detail

presentValue

public double presentValue(SwapPaymentPeriod paymentPeriod,
                           RatesProvider provider)

Description copied from interface: SwapPaymentPeriodPricer

Calculates the present value of a single payment period.

The amount is expressed in the currency of the period. This returns the value of the period with discounting.

The payment date of the period should not be in the past. The result of this method for payment dates in the past is undefined.

Specified by:

presentValue in interface SwapPaymentPeriodPricer<SwapPaymentPeriod>

Parameters:

paymentPeriod - the period

provider - the rates provider

Returns:

the present value of the period

presentValueSensitivity

public PointSensitivityBuilder presentValueSensitivity(SwapPaymentPeriod paymentPeriod,
                                                       RatesProvider provider)

Description copied from interface: SwapPaymentPeriodPricer

Calculates the present value sensitivity of a single payment period.

The present value sensitivity of the period is the sensitivity of the present value to the underlying curves.

Specified by:

presentValueSensitivity in interface SwapPaymentPeriodPricer<SwapPaymentPeriod>

Parameters:

paymentPeriod - the period

provider - the rates provider

Returns:

the present value curve sensitivity of the period

forecastValue

public double forecastValue(SwapPaymentPeriod paymentPeriod,
                            RatesProvider provider)

Description copied from interface: SwapPaymentPeriodPricer

Calculates the forecast value of a single payment period.

The amount is expressed in the currency of the period. This returns the value of the period without discounting.

The payment date of the period should not be in the past. The result of this method for payment dates in the past is undefined.

Specified by:

forecastValue in interface SwapPaymentPeriodPricer<SwapPaymentPeriod>

Parameters:

paymentPeriod - the period

provider - the rates provider

Returns:

the forecast value of the period

forecastValueSensitivity

public PointSensitivityBuilder forecastValueSensitivity(SwapPaymentPeriod paymentPeriod,
                                                        RatesProvider provider)

Description copied from interface: SwapPaymentPeriodPricer

Calculates the forecast value sensitivity of a single payment period.

The forecast value sensitivity of the period is the sensitivity of the forecast value to the underlying curves.

Specified by:

forecastValueSensitivity in interface SwapPaymentPeriodPricer<SwapPaymentPeriod>

Parameters:

paymentPeriod - the period

provider - the rates provider

Returns:

the forecast value curve sensitivity of the period

pvbp

public double pvbp(SwapPaymentPeriod paymentPeriod,
                   RatesProvider provider)

Description copied from interface: SwapPaymentPeriodPricer

Calculates the present value of a basis point of a period.

This calculate the amount by which, to the first order, the period present value changes for a change of the rate defining the payment period. For known amount payments for which there is rate, the value is 0. In absence of compounding on the period, this measure is equivalent to the traditional PVBP.

Specified by:

pvbp in interface SwapPaymentPeriodPricer<SwapPaymentPeriod>

Parameters:

paymentPeriod - the period

provider - the rates provider

Returns:

the present value of a basis point

pvbpSensitivity

public PointSensitivityBuilder pvbpSensitivity(SwapPaymentPeriod paymentPeriod,
                                               RatesProvider provider)

Description copied from interface: SwapPaymentPeriodPricer

Calculates the present value of a basis point sensitivity of a single payment period.

This calculate the sensitivity of the present value of a basis point (pvbp) quantity to the underlying curves.

Specified by:

pvbpSensitivity in interface SwapPaymentPeriodPricer<SwapPaymentPeriod>

Parameters:

paymentPeriod - the period

provider - the rates provider

Returns:

the present value of a basis point sensitivity

accruedInterest

public double accruedInterest(SwapPaymentPeriod paymentPeriod,
                              RatesProvider provider)

Description copied from interface: SwapPaymentPeriodPricer

Calculates the accrued interest since the last payment.

This calculates the interest that has accrued between the start of the period and the valuation date. Discounting is not applied. The amount is expressed in the currency of the period. It is intended that this method is called only with the period where the valuation date is after the start date and before or equal to the end date.

Specified by:

accruedInterest in interface SwapPaymentPeriodPricer<SwapPaymentPeriod>

Parameters:

paymentPeriod - the period

provider - the rates provider

Returns:

the accrued interest of the period
